"I won't argue because you're not rational. The thing you believe in is awful and should cease to exist" is a perfectly fine stance to have about bitcoin and crypto in general.

Its causing massive amounts of pollution, global spikes in price of computer parts, exacerbates shortages in silicon and facilitates all sorts of illegal activity from money laundering to ponzi schemes to trading of illegal goods.

And for what? The shittiest database you could imagine.

My criticism on the original comment is not about his take on crypto, it is about taking that stance about quite literally anything.

If one refuses to argue because they believe the other side is irrational, then abstain for conversation instead of just name-calling/shitting on the thing on a public forum. This is somewhat equivalent to posting some egregious opinion and then saying "don't @ me".

You're assuming a level of good faith in crypto bros that frankly doesn't exist. They aren't interested in any criticism of bitcoin and the like, they personally stand to make money from it and you are just their next potential victim.

I take the dismissive stance you're talking about when dealing with anti-vax, flatearthers, and qanon types. I'm not above that.

Having said that, my original point is the same: then don't engage at all. I don't go posting on flatearther forums how "i won't argue and that their opinion is stupid". I either fully engage and endure what I perceive to be unbelievable stupidity, or don't engage at all.
